Abstract
The present invention belongs to a multifunctional sewage treatment reaction tank. SBR technology is usually used for treating urban comprehensive sewage. In practice, the content of NH4<+>-N of some urban comprehensive sewage is high; the NH4<+>-N needs to carry out anaerobic reaction first. The content of NH4<+>-N of some urban comprehensive sewage is low; when the sewage undergoes the deliverary process, the anaerobic reaction needs not to be carried out first according to the traditional SBR technology. The present invention provides a multifunctional sewage treatment reaction tank which comprises a multifunctional area; the multifunctional area which is identical with an aerobic area is provided with an air supplying pipe and an aeration head; according to water-quality indexes, the multifunctional area can be selectively used as an aerobic area, or an amphoteric and anearobic area or an anaerobic area. When anaerobic reaction needs not to be first carried out to the urban comprehensive sewage, the multifunctional area can be used as the aerobic area; therefore, the sewage treating capability is furthest enhanced, and the integrative cost of sewage treatment is reduced under the premise of ensuring that the water quality of effluent water reaches the standards.
Description
Technical field
The invention belongs to a kind of waste disposal plant, particularly relate to the multi-functional reaction tank that handle a kind of urban comprehensive wastewater.
Background technology
Water is a kind of preciousness but resource very in short supply, if municipal effluent do not add give handle and arbitrarily discharging certainly will cause contaminated water source, worsen environment, influence daily life, even threat to life health.The industrial sewage that the urban comprehensive wastewater generally comprises resident living sewage and discharges through factory's primary treatment adopts biochemical technology usually to the processing of urban comprehensive wastewater.SBR is wherein a kind of microorganism sewage disposal technology according to regular hour order batch operation in reactor that utilizes, and the difference of its principle and traditional activated sludge process is that the waste strength gradient is big in the reaction process.Make microorganism be in saturated with hungry alternating state all the time, help microorganism and be in logarithmic phase, more effectively remove organic pollutant; Make microorganism be in anoxic and aerobic alternation procedure on the other hand, remove ammonia nitrogen and phosphorus effectively.In the treatment system of urban comprehensive wastewater, sewage is mostly by long transport pipe, and sewage is carried in pipeline and in fact promptly is an anaerobic reaction process in the stop of each pumping plant, and while water pump course of conveying has also played stirring action.SBR technology is to realize the plug-flow process from time sequence, and DESIGN OF REACTOR generally includes anaerobic zone, but the size of reactor directly influences sewage treatment capacity.The sewage disposal practice is told us, in some cases the NH in the urban comprehensive wastewater
4 +-N content is higher, need carry out anaerobic reaction earlier; And urban comprehensive wastewater NH under other situations
4 +-N content is lower, and through course of conveying, thereby need not to carry out anaerobic reaction earlier according to traditional SBR sewage treatment process.
Summary of the invention
The present invention is for overcoming above-mentioned the deficiencies in the prior art, proposed a kind of multifunctional sewage treatment reaction tank, can be more suitable for the actual needs of the processing of different influent qualities, guaranteed under the effluent quality prerequisite up to standard, improve sewage treatment capacity to greatest extent, reduce the comprehensive cost of sewage disposal.
Technical scheme of the present invention is: a kind of multifunctional sewage treatment reaction tank comprises multi-functional district, aerobic zone, A partition wall, B partition wall, zone of transition, water inlet pipe, backflow suction Ni Kou and outer spoil disposal suction inlet; Described multi-functional district is optionally as aerobic zone, aerobic area or anaerobic zone.
The identical aerating apparatus that is provided with aerobic zone comprises air-supply duct and aeration head in the nearly bottom in described multi-functional district; Also be provided with air-supply duct and aeration head in described zone of transition; The middle and upper part of described A partition wall and B partition wall is offered some apertures respectively, the number of aperture, size and distribution are to keep current unimpeded, preventing simultaneously that the supernatant liquor flow velocity is too fast and causing the mud disturbance is principle, offer row's square hole respectively in its bottom, to guarantee that every batch flooding quantity can pass through at short notice smoothly, and form active sludge and water mixed liquid preferably, respectively offer two macropores in its underpart, and, make it to guarantee the muddy water mixed solution thorough mixing, the even entire reaction pond in being communicated with communicating pipe; The bottom of described water inlet pipe is directly rushed down mouth and is closed, and on its sidewall a plurality of water outlets is set.
The present invention is provided with multi-functional district, the appropriate design reaction tank, and multi-functional district can select as aerobic zone, aerobic area or anaerobic zone according to the index of influent quality, makes it to be more suitable for the actual needs of the processing of different influent qualities.More traditional sbr reactor pond newly installs to be equipped with still old scrap build no matter be, only increase a small amount of the input, reaction tank just can adapt to the different requirements that change because of influent quality, reaches the purpose that improves sewage load, has correspondingly reduced the comprehensive cost of sewage disposal.
